Time for a round of "Which lines are Kiri-same and which lines are pencils?"

I used Pilot Iroshizuku Kiri-same for the first time the other day and it is wild how much it resembles text made with a pencil. Don't get me wrong, I like it, though I'm not sure how best to use it yet. Crossword puzzles in pen that look like pencil?

So in this image one or more lines are Kiri-same and one or more lines are different types of pencils. Guess which is which.

Line 1: Uni Kuru Toga 0.3 (HB or 2B, I forget)

Line 2: Kiri-same in a Jinhao 80 EF

Line 3: Pentel GraphGear 1000 0.5 (B)

Line 4: A random no-name pencil I found in a drawer
